v o- '1 v V M During *the past few years much attention has been :given tothe'construotion of eyeglass frame's for-supporting lenses. .Some dfthese frameshave been termed-of a-ohanne'l shape to removably'support the lenses -therein.- Other frames have been constructed which support the lenses -'en.tirely from the 430p edge. In e11 of these types of son- :stru'ction', the ideaof 'providingmore area through which the person-using the glassesmay-see prop- -erly, has been carefully considered and the 'appearance-and design have also'been-conside'red of It :Is-e purpose of the present invention t prowide' glasses having frames capable of supporting the lenses byengagemnt therewith over .a relatively smaZll-portionef the circumference of the lenses and to form this construction very simply :to enable the frame to becons'truiztd at a minimum of -cost, =and=to be attached with 'a'minimum ofoaeffort.

v 'ltis a purpose of my invention to construct one form :of :my glasses -in a manner to provide ea :tmme strap extending over the outer surface of the lens along the nasal edge of "the same. This :frame strap is so constructed as toextend close to dzheaedge of the "lens; ?but is so designed vas to provide"attaching means which extend gageth'e lenslatspaoedipointseilong onev-zedgeof the :same.

A bridge I8 connects the frame straps 8, and outwardly extending temple supporting arms [9 may be provided extending outwardly from the arms [3. These temple supporting arms I9 are designed to overlie the rear surface of each of the lenses l5, terminating in pivotal connections 20 to which bows 2| are pivotally attached.

It will be seen that in this type of construction, virtually the entire area of the lenses is open and the fastening means for the lenses engages the inner edges of the lenses adjacent the bridge and nose rests. This construction is exceedingly strong as the portion of the supporting structure or frame to which the lenses are attached is in reality a part of the nose rests and the bridge. The nose rests 22 are connected tothe arms 9 or to the portion [2 by guard arms 23. Thus the nose rests are supported by one end of the lens connection portion of the supporting structure or frame, while the bridge is supported from :the opposite end of the same.

Thelenses' 6 having the attachment projection i. thereon may be formed of glass or of resinous or artificial resinous material such as methacrylate or other suitable plastic and may be formed to any desired contour shape and size. in instances when the lenses ii are formed of glass the connection openings l are preformed therein. In instances when the lenses are formed of a plastic or resinous material the connection openings [5 may be performed or the connecting means such as rivets, screws, or the like may be heated and pressed through the material of the lens with the said lens normally having no connection opening therethrough. This is accomplished by fitting the lens to the lens supporting structure, heating the connecting means and pressing it inwardly of one of the connection openings in the members l2 or M, through the: normally solid lens and through the aligned connection opening in the member 8 after which the said connecting means may be headed over or threadedly connected with the opening in the member 8 in instances when a connecting screw is used. It is, of course, to be understood that the opening in the member 8 is previously provided with a suitably threaded bore.

If desired the various parts of the supporting structure may be all formed integral with each other or may be formed separately and thereafter joined with each other as by soldering, welding or the like. The temple supports or arms I 9 may be shaped to follow the upperrear surface of the lens, the upper peripheral edge of the lens, or the upper front surface of the lens adjacent the upper edge of the lens.

The portions 8 may be placed over the front surface of the projecting portion 1 or overthe rear surface as desired.

In Figure 5 there is shown a frame which is similar to that illustrated in Figures 1 and 2., but in which thelens supporting straps 24 overlie the edge of the projecting portion 1 of the. lens 6. These straps 24 are secured at the top to the temple supports or arms 25, adjacent the opposed ends of the bridge portion 26, the said temple supports 25 having temple connection ends 21 thereon. p g

Opposed sets of ears 28 having aligned cone nection openings therein are secured to the straps 24 adjacentthe upper ends and lower ends thereof and engage the opposite surfaces of the projection 1 of the lenses 6 and are connected theretoby rivets, screws or the like in a manner similar to the first structure set forth above. The depending portions 24, adjacent the lower ends thereof, are provided with rearwardly extending nose pad supporting arms 29.

In accordance with the patent statute I have described the principles of construction of my eyeglasses, and while I have endeavored to set forth the best embodiments thereof, I desire to have it understood that these are only illustrative of a means of carrying out my invention and that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
